1590A Buffered Bypass Looper

I am wanting a way to add a buffered output to the input of my Roland RE-201 Space Echo and utilize a bypass. The Space Echo does have its own external bypass switch but you signal still passes through the Space Echo. I wanted something with true bypass but a buffer on the effect output. I chose to use the simple Klon buffer on a layout by Storyboardist. But there is a catch, I want all this to fit in a 1590A enclosure. I messed with some calipers and my drill template in photoshop until I got a nice tight design and did a prototype. So far everything is coming together great. I chose to go with the optical bypass Lumen PCB by Grind Customs since I love the DPDT switches.
